摘要

摘要: 城市生活垃圾分类处置作为城市固废资源化、减量化的重要举措,是助力减少温室气体排放、实现碳中和碳达峰目标的关键一环。经过上海的试点摸索,有效结合再生资源利用网络和城市环卫网络的“两网融合”回收模式显现出减碳优势。但目前有关生活垃圾碳排放的研究仅局限于地区范围,全国时空框架下的温室气体排放核算体系较少,缺乏精确性与统一性,大多研究的核算指标和参数亟待更新。由此构建了“1+4+8”的城市调研脉络,结合实地考察、政策和文献调研,建立中国生活垃圾分类处理过程温室气体排放核算体系。通过数据分析探究了“十三五”期间全国各省市自治区生活垃圾的碳排放情况,并进一步预测“十四五”期间应用“两网融合”的减碳潜力。结果表明:“两网融合”前后垃圾处理的减碳效应(碳排放系数)由0.71 kg CO₂-eq/t转变为1.56 kg CO₂-eq/t;当全国各省市自治区“两网融合”覆盖率达到10%时,预期2025年全国各省市自治区所能贡献的减碳潜力将达到1310万t。依据总结出的“上海经验”为不同层级城市群给出了针对性的导向建议,以期助力全国生活垃圾处置全生态流程中的节能减排和协同增效。

Abstract: As an important initiative to reuse and reduce municipal solid waste, municipal solid waste classification and disposal is a key component in reducing greenhouse gas (GHG) emissions in the waste disposal process and achieving the goal of carbon neutrality and carbon peaking. After a pilot study in Shanghai, the "Two Networks Integration" model, which effectively combines the recycling network and the city sanitation network shows its advantage in reducing carbon emissions. However, the current research on carbon emissions from China’s domestic waste is only limited to the regional scale. Fewer greenhouse gas emission accounting systems, most of which lack accuracy and uniformity, are available in a national spatial and temporal framework. Meanwhile, most of the accounting indicators and parameters need to be updated. This project was based on a "1+4+8" urban research approach, combining fieldwork, policy, and literature research, to establish a GHG accounting system for domestic waste classification and disposal in China. The research explored the carbon emissions of domestic waste in each province and city during the 13th Five-Year Plan period through data analysis, and predicted the carbon reduction potential of the application of the "Two Networks Integration" model during the 14th Five-Year Plan period. The results showed that the carbon reduction effect (in terms of carbon emission factor) of waste treatment before and after the "Two Networks Integration" changed from 0.71 kg CO₂-eq/t to 1.56 kg CO₂-eq/t. It was expected that, if the coverage rate of the "Two Networks Integration" reaches 10% in China, the carbon reduction potential contributed by all regions would reach 13.1 million tons in 2025. The research also provided targeted recommendations based on the "Shanghai Experience" for different levels of city clusters to reduce energy consumption and increase synergies in the whole process of domestic waste disposal nationwide.
